LITTLE ROCK — Early voting begins for Arkansas' primary and nonpartisan judicial election in what's expected to be the first statewide test of a new voter ID law.

Voters can cast ballots early starting Monday for the state's May 20 primary. Voting begins days after a Pulaski County judge ruled that a new law requiring voters to show photo identification at the polls was unconstitutional, but said he wouldn't block the state from enforcing the law during the primary.

Pulaski County Circuit Judge Tim Fox had previously voided the law in a separate case, but that ruling was stayed by the Supreme Court as it considers an appeal.

The primary is highlighted by several hotly contested Republican primaries for statewide and congressional offices.
